Abstract Students usually have plenty of experience
with online social technologies, but they lack understanding about how to use these tools and methods for course learning. This ar- ticle is designed to help college students who are anxious about participating in an online learning community or do not know how to build one effectively. With ideas derived from research and practice, this guide has been written to inform online students about learn- ing communities, the benefits they offer, and how students can assist in building a success- ful online community.
Keywords: online learning community, online learning, community of practice, CSCL, computer-supported collaborative learning, self-regulation, netiquette, social learning.
any college students struggle to use on- line technologies in their formal distance learning courses. The problem for many is
not a lack of familiarity with online technologies, as over 80% of students use Facebook (Anderson Analytics, 2008), 40% use MySpace (Anderson Analytics), and many use Yahoo/Google groups, discussion boards, and instant messaging. How- ever, these students are unsure how to use online sharing/collaboration tools for learning in their college courses. As they enter a learning com-
munity, many report feeling like the title of an article about online students: “Engagement, Ex- citement, Anxiety, and Fear” (Conrad, 2002).
This article is intended to help college stu- dents understand how to strengthen the learn- ing community in an online course that has been designed to allow rich student interac- tion. While many articles and books have been written to help instructional designers and teachers build effective online communities (e.g. Bonk, Wisher, & Nigrelli, 2004; Dawes & Sams, 2004; Hildreth & Kimble, 2004; Lewis & Allan, 2005; Lowry, Thornam, & White, 2000; McConnell, 2006), guidelines need to be directed to the new online students them- selves, providing guidance in learning how to learn online (Palloff, 2001). This article may be distributed by instructors to college students entering an online course to teach them about what online learning communities (OLCs) are, why they benefit learners, and how students can contribute to strengthening a success- ful online community. While this article was written for college students, it may have some applicability to high school students as well. What Is an Online Learning Community?
Researchers have been arguing for decades about what defines a community (Hillery, 1955). Some consider a community to be per- sons within a shared physical or virtual space (Lichenstein, 2005; Rheingold, 1993; West,

2007), while others have argued that community is defined by feelings of trust, respect, or relation- ship (Glynn, 1981; Hill, 1996; Sarason, 1974). This article is based on this last definition because col- lege students often do not control their access to other members of an online class, as that is typi- cally an instructor’s decision. However, when a course instructor chooses to organize class activi- ties so online students can interact, then the stu- dents need to build the emotional bridges of trust and relationships with each other (Liu, Magjuka,
Bonk, & Lee, 2007) to cre- ate a stronger, more effec- tive learning community.
Online Learning Communities (OLCs) are similar to and different from face-to-face (F2F) learning communities in many ways. Some of the biggest differences are that OLC members often communicate through text rather than spoken dialogue, and OLC con- versations are timed dif- ferently—varying from in- stantaneous (synchronous chatting) to lasting hours or days (email or discus- sion boards). Another dis-
concerting difference to new online learners is access to the online teacher. Instead of walk- ing into a classroom where the teacher is vis- ibly present, online students will often interact with each other and the content without know- ing when or if the teacher is watching. While teachers may technically be more accessible online through email, discussion forums, or even chat, they may choose to take on more of a facilitative role. This may make them less vis- ible than in a face-to-face course, while allow- ing the students greater autonomy in working together (Palloff & Pratt, 2001).
Why Are Online Learning Communities Important?
Online learning can include everything from independent study with limited interac- tion to vibrant, interactive communities in which students know and support each other and co-construct knowledge together. With different options available in online educa- tion, why should students invest the effort in strengthening a sense of community in their online courses?
The first reason is because strong OLCs can help students overcome a sense of isolation that online students traditionally feel (Canada,
2000; Liu, Magjuka, Bonk, & Lee, 2007; Weiss, 2000), and lead to more reflective discourse (Hawkes, 2006). In addition to helping stu- dents feel more connected, research has found that learning communities can lead to higher student engagement, greater respect for the di- versity of all students, higher intrinsic motiva- tion, and higher learning outcomes in the areas that are most important (Watkins, 2005). Pall- off and Pratt (2001) found that OLCs “[increase] the likelihood that [students] will stay involved and motivated” (p. 138), while Liu et al. (2007) reported that when some students indicated feeling a strong sense of community, they also perceived themselves to be more engaged, sat- isfied, and successful in their learning (see also Moisey, Neu, & Cleveland-Innes, 2008).
How Can Students Strengthen Their Online Learning Community?
Recognizing the importance of learning communities is necessary but not sufficient, because building online learning communities requires effort (Schwen & Hara, 2004). Follow- ing are suggestions for strengthening an on- line community from the inside out—through actions of the students within the community. When instructors design courses that encour- age student interaction, the strength of the community that emerges often depends on how the students engage with each other and with the course (Liu et al., 2007). Students can best build an online learning community by focus- ing on four types of interactions involved with every successful OLC: learner-learner interac- tion, learner-content interaction, learner-teach- er interaction, and learner-tool interaction (see Moore, 1993, for a discussion of three of these interaction types). A stronger emphasis is placed on learner-learner interaction skills, as this is often the area over which the students have the most control and where there are more op- portunities for strengthening the psychological sense of community.
Learner-Learner Interaction Learner-learner interactions are a critical
factor in creating a strong learning commu- nity (Conrad, 2005; Gorsky, 2004) with effec- tive group problem solving (Merrill & Gilbert, 2008). The first step to effective learner-learner interaction is understanding etiquette specific to online communication (netiquette). Just as face- to-face communication follows unwritten but acknowledged standards, such as taking turns when speaking, courteous cyberspace commu- nication involves important unwritten rules. A critical courtesy is to always assume good in- tent of the person posting a comment or send- ing a message (Palloff & Pratt, 2001). Without
“Instead of walking into a classroom
where the teacher is visibly present, online
students will often interact with each
other and the content without knowing
when or if the teacher is watching.”

nonverbal and auditory cues, text messages can often be misunderstood because they lack the emotional richness of context (Zembylas, 2008). Thus, it is helpful to wait at least 24 hours before responding to an attack, which could threaten to destroy the community, because “the intensity of the message always seems to wane with time” (Palloff & Pratt, 2001, p. 150). Ignoring this prac- tice often leads to flaming, or posting of critical and angry personal attacks, which can destroy the community (Shea, Swan, Li, & Pickett, 2005).
Other important netiquette guidelines refer to timing. Much online communication is asynchronous, but most of our daily living happens synchronously and asynchronous timing can be jarring. The person expect- ing a response should be patient about delays, which may be caused by the other person be- ing sick, on vacation, busy at work, or unable to frequently check messages. Especially on weekends, community members should not expect prompt answers. However, when a re-

sponse is expected the recipient should attempt to respond as quickly as possible, even if to say, “Good question. I’ll think about it and post something tomorrow.” Short messages such as this can be equivalent to nodding one’s head to show attention during F2F communication. Other important netiquette guidelines are pro- vided in Figure 1 on the previous page.
Because, “community is defined by the rela- tionships and interactions between and among people,” (Liu, et al., 2007, p. 11) students build- ing an OLC should take the time to develop rela- tionships with other members of the community (Lowry et al., 2000). Researchers agree, “online groups are often more effective if they are ini- tially formed by some type of face-to-face meet- ings,” (Clarke, 2004, p. 14; see also Conrad, 2005). However, if this is not possible many OLCs have places where students can post their pictures or short biographies. Simply having a picture at- tached to messages can strengthen the recogni- tion that there is a human being, with emotions, thoughts, and histories, behind the text.
Many online communities have a designat- ed space for members to socialize about topics not related to the course content. Often these spaces are most beneficial if they are for stu- dents only, not instructors. This allows students to have the kinds of informal discussions that they might normally have in the hallways before an F2F class begins. Examples of such informal social spaces are available in Tappedin (http:// tappedin.org/tappedin/), the online profession- al community for teachers. In Tappedin, there are formal learning spaces (such as the Arcade Conference Room), and informal spaces (such as the Hot Tub). This differentiation of spaces lets community members know what type of dialogue is encouraged in each space. In on- line communities without visual interfaces like those of Tappedin, an informal discussion can be as simple as a chat room or discussion thread designated as the water cooler to encourage the kind of informal discussion in that forum that typically happens in work environments as co- workers meet around the water cooler or coffee machine. Participants can greatly improve their connection to each other by spending some
time in this informal space, especially at the be- ginning of the semester.
Text messages can seem more human with the addition of humor and honesty, emoticons, and personal and expressive language. To make messages more personal, an individual can frame a message by bracketing comments to explain the intended tone of a message: [“I’m just joking here”], for example (Palloff & Pratt, 1999; Weiss, 2000). In addition to making online speech more natural and human, critical listening is impor- tant. Kramer (2002) suggests that students can be better critical listeners online if they are (1) mentally awake and prepared to participate, (2) willing to ask questions, and (3) aware of filters, such as biases, judgments, and attitudes that af- fect how they interpret messages.
Perhaps most important is to remember that there are three functions of online commu- nities, and efficient accomplishment of a task is only one of them. Online communities also ex- ist to support the members and to take care of individual needs (Palloff & Pratt, 2001).
Simply interacting with one an- other is not enough. . . . Participation in an online course is not the same as collaboration. Collaboration goes be- yond direct engagement in specific ac- tivities and is consistent throughout the course. It is a process that helps students achieve deeper levels of knowledge gen- erations through the creation of shared goals, shared exploration, and a shared process of meaning-making. (Palloff & Pratt, 2003, p. 23) It is through collaboration, not simply in-
teraction, that students have the best learning experiences. Part of effective collaborative, or cooperative, learning is developing a sense of trust and interdependence among communi- ty members (Weidman & Bishop, 2009). This strengthens the community (Dirkx & Smith, 2004) and helps members construct their iden- tities as community members (Wenger, 1998). Students can develop this interdependence by relying on each other, rather than the instructor, for simple tasks and questions. Relying on peers during instructional discussions can make in-
“Students can best build an online learning community by focusing on four types of interactions involved with
every successful OLC: learner-learner interaction, learner-content interaction, learner-teacher interaction,
and learner-tool interaction…”
Volume 54, Number 5 TechTrends • September/October 2010 73
teractions more meaningful (Seo, 2007). When content misunderstandings do require the in- structor’s input, the group can approach the in- structor together. When learning communities develop this interdependence, instructors can avoid having to stamp out little fires and instead can provide quality instructional feedback in the most critical areas.
Learner-Instructor Interaction Learner-instructor interactions are also
critical for effective student learning in OLCs (O’Leary & Quinlan, 2007). Swan (2002) found that interaction with the instructor was one of three factors significantly related to student per- ceptions of the course. Online instructors estab- lish their social presence through multiple ways, including the instructional design of the course, organization of the materials, and directed facil- itation of the activities (Shea et al., 2005). Thus, the instructor may not always communicate di- rectly with each online student but may establish connections with each of them in other ways. When students recognize their instructor’s ef- forts to create teaching presence, their sense of community can improve (Shea et al., 2005).
Additionally, many of the same recom- mendations for learner-learner interactions also apply to learner-instructor interactions, par- ticularly regarding netiquette, communication timing, and making efforts to establish greater social presence online through pictures, bio- graphical sketches, and informal conversation at the beginning of the semester. This helps the instructor understand the students’ needs, per- sonalities, and learning goals.
Finally, successful learner-instructor inter- action clarifies expectations, establishes pro- cedures, and defines community rules. This is part of what is typically called the norming period of group relationships (Tuckman, 1965) where community members define the norms of their learning community. Students can contribute to successful norming with their peers and instructors by sharing their opinions early in the semester —and asking instructors for theirs—about how often communication should take place and in what format. Addi- tionally, students can ask questions to clarify the expectations for participation and collabo- ration. Because of the faceless nature of online learning, developing these norms can prevent future misunderstandings.
Learner-Tool (Technology) Interaction Tools, including modern technologies, are
always important mediators within problem- solving communities, especially in online learning communities where technology plays
a visible role. Because technology is critical to the online community, students’ interactions with the technology are important. Many stu- dents choose to take academic courses online because doing so is less expensive and more convenient than moving on site. However, despite being economical, students should be prepared to invest in the appropriate tech- nology to allow them to be full community participants. It is not fair to other members of the learning community if a participant is using a slow Internet connection, an outdated computer, and incompatible software, it could make it very difficult to collaborate with oth- ers and may force the individual to withdraw from the community because of technologi- cal barriers. Student OLC members should expect to invest in the right tools to engage in the community (Dirkx & Smith, 2004).
In addition, students should take respon- sibility for knowing how to use the technol- ogy. Conrad (2005) reported that new online learners often are preoccupied with functional and technical concerns. Students who are un- familiar with the technologies or the instruc- tional medium should invest some time up front mastering these tools so they can focus on their learning. This is important because “frequent technical failures or connectivity issues may leave members out of the com- munity gathering place and thus hinder the development of a sense of community,” (Liu et al, 2007, p. 12). Sometimes technology can become a scapegoat when things go wrong (Dirkx & Smith, 2004), even though the reali- ty may be that the students did not sufficiently prepare themselves to use the tools.
No matter how skilled students are with technology, they should expect that technology will—not may—fail some of the time. To avoid anxiety, community participants should con- scientiously save documents and even discus- sion board posts in separate locations. Before scheduled synchronous chats or conferences, all should test their technology setup or login, so that precious group discussion time is not wasted with technical glitches.
Learner-Content Interaction The final type of interaction in an OLC is
between learners and content. In OLCs, stu- dents must exhibit greater self-regulation in studying the course content. Canada (2000) states, “The online student, however, cannot live by RAM alone. Even more importantly [than tech skills] is the ability to manage time and work effectively” (p. 36). Self-regulation is highly correlated with success in online learn- ing communities (Anderson, 2007). Because of

the nature of OLCs, teachers may be less pres- ent, deadlines may be softer, flexibility may be greater, and homework may be oriented to- wards more self-directed problem solving. In this environment, students who do not care- fully monitor their own learning can lose track of time, fall behind, and become overwhelmed or intimidated (Gabriel, 2004). They also have less external motivation to develop relation- ships with other members of the community,
since they cannot see faces waiting for responses. As Canada (2000) described it, the traditional learner is much like an athlete who is constantly under the coach’s observation and so is highly motivated to keep performing. The on- line learner, in contrast, is
much like a pianist practicing in private for a recital that will come at a future, possibly un- determined, date.
Lowry and colleagues (2000) recommend- ed that members of online communities set their own deadlines to help them stay motivat- ed. Just as in physical communities, members of a virtual community can offer to give peer critiques of assignments, which would require self-imposed deadlines so that students stay on schedule. If the teacher does not have assigned topics or roles for discussion, the community members can select these topics and determine who will fill the rotating moderator role. Many researchers feel that focusing comments — and perhaps even labeling them as particular kinds of messages or responses — can lead to more effective online dialogue (Jeong, 2004).
Finally, by understanding the technolo- gies and medium used for the course, stu- dents can often find more efficient ways to interact with the content. This is important because a main challenge in online learning is managing all of the reading (Gabriel, 2004). By understanding the course technologies, students can often discover ways to use RSS syndication to search, sort, and aggregate con- tent into “customized and personal views of emerging content” (Anderson & Kuskis, 2007) that can help students regulate and organize their learning. Also, by using descriptive and meaningful titles in discussion board posts, students can alert their peers to what their comment is about, whom it is for, or what it is responding to.
Summary Online learning is firmly entrenched in
the United States educational system (U.S.
Department of Education, 2003). Thousands of students who are enrolled in online classes and academic programs are in danger of feeling disenfranchised, isolated, and unsupported in their learning. An effective method for address- ing these difficulties is through an active online learning community, but instructors cannot build these communities alone. The success of an online community depends on the efforts of its members to build it. As Palloff and Pratt (2003) wrote,
The virtual student needs to ac- cept the different role of the instructor online and recognize that the deepest learning in an online course comes from interacting with everyone in- volved. Reaching that level of under- standing, and being willing to take on responsibility for creating the learning community as a result, is critical to its formation. (p. 20). The guidelines in this article can help stu-
dents understand what it means to learn in an online community, as well as what the commu- nity should expect of them. This may help learn- ers get past simply having an “experience that is shared” and progress towards something much more meaningful: “creat[ing] a shared experi- ence,” (Schrage, 1990).
